Just had the truck tuned up and it was running great. Now it only runs for about 4 mimites and stalls. Its an 89 350 TBI. I have a post up in the garage " I HATE WHEN MY TRUCK RUNS GOOD" and a couple of people suggested the HEI module which I did tonight but that did not help. I also replaced the fuel filter. Any thoughts would be helpful. Thanks Maybe time for a rebuild kit for Malory Fuel pump, if they make them. If this one is croaking I'm not shore if I will get another Malory its only about a year old and was kinda expensive.
